Low Noise Amplifiers (LNAs) are commonly used in the front-end of radio frequency (RF) communication receivers to amplify information-bearing signals above the noise floor before the signals are processed. They are found in the receivers of both wired and wireless communication systems. Increasingly, wideband wide range RF receivers are used in broadband communication transceivers to receive signals with a large bandwidth, such as ultra wideband (UWB) signals. These wideband RF receivers need LNAs with extremely tight noise and linearity specifications. These requirements become even more stringent when wideband signals have high dynamic range. For example, received signals may have a power level that varies from −90 dBm to +10 dBm, leading to a 100 dBc in dynamic range. However, in LNA designs, there is a delicate tradeoff between amplifier gain, noise and linear characteristic of the LNAs that makes the attainment of both high linearity and low noise difficult. Amplifying high dynamic wideband signals injects noise, further complicating the design tradeoff. As such, it is desired to have LNAs with high linearity and low noise for wideband receivers that receive high dynamic range signals.
